I have 2 XL4's, one Tivo HD, and 1 Roamio Pro. They all connect to each other, to the network and handle room to room transfers well.

I just bought a new Roamio from TiVo.com It was delivered on Tuesday. I installed it on Tuesday, activated my new unit on TiVo.com, and paired the cable card on Tuesday. Waiting 24 hours, Wednesday night, I forced a connection on all my units and afterwards I restarted all units. I then went on TiVo.com and used the season pass manager to transfer passes to the new Roamio. (it worked great).

The new Roamio can "see" the other TiVo's in the network under "My Shows", but they are "orange exclamation point" "!"... and gives me a "cant connect c423 error". I called TiVo and they forced a connection to all my units on their end, and said to call back in 30 minutes. I went to sleep.

10 hours later - still the same problem. Before I call tech support, does anyone have a suggestion on how to resolve this?

I just checked my wireless signal on the Roamio settings - it is at 24 % (marginal). even though its 3 feet from the router ?? Would that be the cause of the issue?

Be careful and make sure it isn't a "green" switch. If it has 'green' in the product name or on the packaging or has any type of 'eco' wording, earth icon, or green leaf symbol you might want to pick a different model to avoid any potential issues.
